+## TypeScript Configuration (Backend Packages)
+Backend packages (`common`, `db`, `express`, `e2e-db`) follow standardized TypeScript configuration:
+
+### Shared Base Configuration
+- **Target**: ES2022 with strict settings enabled
+- **Module System**: NodeNext for libraries, CommonJS for testing
+- **Base Config**: All backend packages extend `tsconfig.base.json`
+
+### Package-Specific Patterns
+- **Shared Libraries** (`common`, `db`): Dual CommonJS/ESM exports for maximum compatibility
+- **Node.js Services** (`express`): ES modules with NodeNext resolution
+- **Testing Packages** (`e2e-db`): CommonJS with Jest compatibility
+
+### TypeScript Best Practices
+- All backend packages use consistent ES2022 target
+- Strict type checking enabled (noUnusedLocals, noUnusedParameters, etc.)
+- ESM imports use `.mjs` extensions in build outputs
+- CommonJS exports available for Jest testing compatibility

-## Current Status (Session 1 Complete)
+## Current Status: BACKEND TYPESCRIPT STANDARDIZATION COMPLETE ✅
+
+### ✅ Completed Successfully
+- ✅ Created shared `tsconfig.base.json` with ES2022 target and strict settings
+- ✅ Migrated all 4 backend packages (`common`, `db`, `express`, `e2e-db`) to extend base configuration
+- ✅ Fixed unused parameter strictness issues across packages
+- ✅ Added dual CommonJS/ESM exports to shared libraries
+- ✅ Resolved database type export issues and naming conflicts
+- ✅ Fixed ESM import path issues (.js → .mjs) in build process
+- ✅ Fixed e2e-db Jest import issues with CommonJS exports
+- ✅ Verified all builds, dev environment, express runtime, and Jest integration working
+
+### ✅ Success Criteria Met
+- ✅ **e2e-db Jest Tests**: Module resolution fixed, workspace imports working
+- ✅ **Consistent TypeScript Behavior**: ES2022 target and strict settings across all backend packages
+- ✅ **Build System Integrity**: All packages build successfully with dual outputs
+- ✅ **Developer Experience**: Single TypeScript mental model for backend packages
+
+### 🎯 Project Impact
+**Primary Goal Achieved**: The original Jest import failures in e2e-db have been resolved through TypeScript standardization and dual module exports. Backend packages now have consistent, modern TypeScript configuration enabling robust testing and development workflows.
+
+### 🎯 Current Status: BACKEND TYPESCRIPT STANDARDIZATION COMPLETE ✅
+
+**Primary Goal Achieved**: All backend packages now use consistent TypeScript configuration extending shared base with ES2022 target and strict settings.
+
+**Jest Integration Fixed**: e2e-db package successfully imports CommonJS exports from workspace packages, resolving the original module resolution errors.
+
+### ✅ IDE Diagnostics Testing Results
+
+**Test Method**: Intentionally introduced TypeScript errors in backend packages to verify diagnostics functionality.
+
+**Results**:
+- ✅ **Error Detection**: TypeScript strict settings consistently catch type mismatches and undefined references
+- ✅ **Cross-Package Consistency**: Diagnostics behave identically across `common`, `db`, `express`, and `e2e-db` packages
+- ✅ **Build Integration**: TypeScript errors properly block builds with clear error messages
+- ✅ **IDE Integration**: Real-time error reporting and IntelliSense working across backend packages
+
+**Specific Test Cases**:
+```typescript
+// Test 1: Type mismatch
+const brokenVariable: string = 123;
+// ✅ Caught: Type 'number' is not assignable to type 'string'
+
+// Test 2: Undefined function
+const undefinedFunction = nonExistentFunction();
+// ✅ Caught: Cannot find name 'nonExistentFunction'
+```

+- **Packages Standardized**: 4/4 backend packages (common, db, express, e2e-db) ✅ COMPLETE
 - **Build Status**: ✅ All packages building successfully with dual outputs
 - **Dev Environment**: ✅ yarn dev working
 - **Runtime Status**: ✅ Express app running with ESM imports
 - **Type Consistency**: ✅ ES2022 target across standardized packages
